HAVE I GOT THE SOLUTION FOR YOU! I have developed (still developing) an enterprise level application to do just this task. There are two versions, one is quite simple and forks a number of child processes that ping and report the result. It currently responds with SNMP traps to our monitoring software.
The second one works much the same but is much more intellegent and can report on the accumulation of errors. Say that a level one error is 7 failures in 10 minutes and a level two is 12 in fifteen for example. Again, it sends an SNMP trap, but that section could just be cut out.
They are not 'done' yet but work perfectly fine. Just a little rough on the user interface side. I will post them here. Let me know if you have questions. I planned on posting this once it was 'done' but since you have a need.....
Please be advised, this was written for and on Unix and will require slight porting to Win.
